telephony

   <communications> Communication, often two-way, of spoken
   information, by means of electrical signals carried by wires
   or radio waves.  The term was used to indicate transmission of
   the voice, as distinguished from telegraphy (done in {Morse
   code} and usually called "{continuous wave}" or CW
   transmission), radio teletypewriter (RTTY) transmission (also
   called FSK for "{Frequency Shift Keying}", the modulation
   scheme used by such machines), and later, facimile.
